Milklove is on the first episode of this. It's also a stand-alone sequel to their story from Bad Buddy. It'd be worth giving this a try before/after jumping into 23.5.
This is Milklove's first series as a couple. While they do not have as much screentime, this series did give viewers the chance to experience Milklove's chemistry for the first time.
They are both Thai series centered on relationships between sapphic couples. They do capture different settings, but it seems like a better recommendation for people who are interested in seeing more GL series.
They're both GMMTV actors who have their own lifestyle vlog type of show where they invite their friends.
